Question

based on the graph, what is the approximate number of bacteria after 16 hours?
6 bacteria
8 bacteria
60 bacteria
80 bacteria

Explanation:

Step1: Locate 16 on x - axis

Find the value of 16 on the time (x - axis) of the graph.

Step2: Read corresponding y - value

Move vertically from x = 16 until intersecting the curve, then move horizontally to read the corresponding value on the y - axis (number of bacteria). By observing the graph, when x = 16, the y - value is approximately 60.

Answer:

60 bacteria
